Bad English warning!
My Tarkov used to crash after 1-2 hours of gameplay along with all my apps running at the same time – Spotify, LOL client, or Chrome were turning into visually bugged black/green squares.
It turned out that my Windows Pagefile was set to "Automatic" and Windows decided to leave it on 2,3GB – turned out it's not enough! I had to set it manually at 24GB for both initial and max size on my System partition only (C:) and BOOM!, everything is working fine now, no crashing and my virtual and physical memory usage dropped significally! 🙂
You can use this guide if you don't know how to do this –
Sorry for my English, but I hope this little fix will help some of you 🙂
